cds-question@unistra.frg-starsasteroseismologyeffective-temperatureThe KEYSTONE project aims to enhance our understanding of solar-like oscillators by delivering a catalogue of global asteroseismic parameters ({Delta}{nu} and {nu}_max_) for 173 stars, comprising mainly dwarfs and subgiants, observed by the K2 mission in its short-cadence mode during campaigns 6-19. We derive atmospheric parameters and luminosities using spectroscopic data from TRES, astrometric data from Gaia, and the infrared flux method (IRFM) for a comprehensive stellar characterisation. Asteroseismic parameters are robustly extracted using three independent methods, complemented by an iterative refinement of the spectroscopic analyses using seismic log(g) values to enhance parameter accuracy. Our analysis identifies new detections of solar-like oscillations in 159 stars, providing an important complement to already published results from previous campaigns. The catalogue provides homogeneously derived atmospheric parameters and luminosities for the majority of the sample. Comparison between spectroscopic T_eff_ and those obtained from the IRFM demonstrates excellent agreement. The iterative approach to spectroscopic analysis significantly enhances the accuracy of the stellar properties derived.2024A&A...688A..13Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/688/A13CatalogResearchIsServedByTAP VizieR generic servicerelated-toB/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2020)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)I/347 : Distances to 1.33 billion stars in Gaia DR2I/350 : Gaia EDR3 (Gaia Collaboration, 2020)I/352 : Distances to 1.47 billion stars in Gaia EDR3III/284 : APOGEE-2 data from DR16 (Johnsson+, 2020)IV/34 : K2 Ecliptic Plane Input Catalog (EPIC) (Huber+, 2017)J/A+A/530/A138 : Geneva-Copenhagen survey re-analysis (Casagrande+, 2011)J/A+A/616/A7 : Gaia DR2 radial velocity standard stars catalogJ/AJ/153/21 : Abundances in the local region.
